sonar signal cone, the image appears on the screen as a long line in- stead of a fish arch. Reducing the chart speed may result in a shorter line that more closely resembles a regular fish return.
To adjust Chart Speed, repeatedly press MENU until the CHART SPEED scroll bar appears. Press ↑ to increase the speed of the chart. Press ↓ to decrease it. Press PWR to clear the menu.
To return to the original setting, repeat the steps above, but use the arrow keys to set the speed to 100% before clearing the menu.
Frequency
Your sonar unit can transmit signals at 83 kHz and 200 kHz. The de- fault frequency is 200 kHz, best used in shallow water (about 300 feet or less). This frequency is the best choice for about 80 percent of the fresh and salt water sport fishing applications. When you get into very deep salt water, up to 1,000 feet, the 83 kHz frequency will work best.
The 200 kHz transducer will give you better detail and definition, but less depth penetration. You will not get as much detail or definition with the 83 kHz frequency, but it has greater depth penetration and up to 120° of wide fishingfinding coverage. Remember, all sonar units typically read deeper in fresh water than in salt water.

To switch the Frequency, repeatedly press MENU until the Frequency menu appears. Press ↑ to select 200 KHZ or press ↓ to choose 83 KHZ. Press PWR to clear the Frequency menu from the screen.
Fish I.D.
The Fish I.D. feature displays — as fish — targets that meet certain conditions. The microcomputer analyzes all echoes and eliminates sur- face clutter, thermoclines and other undesirable signals.
